SUPPLEMENTAL TIRE ron VEHICLE-WHEELS.

To all whom it may concern Be it-known that I, CLIVE HAs'rINoS, a

citizen of the United States, residing at Atchison, in the county of Atchison and State of Kansas, have invent-ed new and useful Improvements in SupplementalTires for Vehicle-Wheels, of which the following is a specification.

This invention relates to supplemental tires for vehicle wheels, and more partlcu- 'larly to wheels with pneumatic tires whereby the vehicle, such as an automobile, may

be quickly and easily converted from its adaptation to ordinary road use so as to be applicable for use upon the rails of a railroad track.

'The main object ofmy invention is to provide metal flange tires so constructed as to enable a railroad oilicial, or other person,

to attach the same quickly and securely to the wheels of an automobile and thereby adapt the vehicle for use upon railroad tracks, and after the run on the tracks has been made, to permit'of the easy removal of the metallic flange tires so as to allow the automobile to continue its way over ordinary roads. f

With this and other objects in view, the invention consists in the construction. and

' novel combination and arrangement of parts portions, and minor details may be resorted to within the scope of the invention.

In the accompanying drawings, forming a part of this specification,Figures 1 and 2 are, respectively, side and edge views of my invention. Figs. 3 and 4 are enlarged viewsin cross section.

In the construction shown, 1 represents an annulus of any'suitable material, made in .one piece, which may encircle-the automobile tire 2 on the outside of the wheel. The greater part of the inner surface ofthe a.n nulus 1 is curved as at 3, so that it shall substantially conform to the shape of the tire when the latter is inflated. The outer ortread surface of the annulus has a con ti-iiuous flange 4 for engagement with the side of the railroad rail, and a portion 6,-

the outer surface of which is adapted to engage the top of the rail. It will be seen that the annulus 1, when. placed upon the Specification of Letters Patent.

I Application filed April 29, 1914. Serial No. 835,184.

the ordinary car Wheel as far as the tread surface and flange are concerned.

.I will now explain the preferred means by which the annulus 1 is held firmly upon the tire. Upon the inner surface of theannulus 1, and preferably directly over the flange 4, as shown in the drawings, is a groove 5 running continuouslyaroundsthe annulus. After the annulus has been placed upon that-ire, an inner annulus 7, having a tongue. 8, is changed from its position as shown in Fig. 4 to that represented in Fig. 3. By meansof the tongue 8 and groove 5 the annulus 7 "and annulus 1 with their inner curved surfaces 9 and 3,-respeotively, shaped to fit the inflated tire, will make a complete holding'surfacefor the tire. Preferably the inner annulus 7 is composed of two'sections, 10. and 11, although a greater number may be employed. Upon one of the sections of the annulus 7 at its respective ends are lugs '12, and at the ends of the other section are lugs 13 bored out and tapped so as to permit.

a screw 14,to be run therethrough. After the sectional annulus 7 has been fitted upon the annulus 1, as shown in Fig. 3, the screws 14 are tightened up, and by means of the points 15, hearing against the lugs-12, the sections 10 and 11 of the annulus 7 are pushed apart, thus firmly pressing. the

tongue 8 into-the groove 5. Thus it will be seen that the annulus 1 withits tread sur-' face and flange, and the inner annulus], serve. to make a strong metal tire 'ifor automobile wheels adapted for use upon railroad rails. The danger of the metal tire off the automobile wheel is reduced "tothe;

minimum, and its simplicity of construction enables itsattachment to or detachment from vehicle wheels to be made'in a few minutes.

While I have herein shown and particularly described the preferred embodiment of my invention, I do not wish to be limited to {)he' precise details of construction shown;

Having described my invention, I claim as y to fit over the tread of the vehicle wheel tire,

one of said members consisting of an annulus having a flange and a tread,,and the other, consisting of an annulus adapted to be attached to the aforesaid annulus, and means to clamp the said members together.

2. A supplemental tire for vehicle wheels comprising two separable members adapted to fit over the tread'of the vehicle wheel tire, one of said members consisting of a onepart annulus having a flange and a tread, and the other consisting ,of a sectional annulus adapted to be attached to the aforesaid onepart annulus, and means to clamp said members together. I

3. A supplemental tire for vehicle wheels comprising two separable members adapted to fit over the tread of the vehicle wheel tire, one of said members consisting of an annulus having a flange and a tread and a groove extendingaround its interior surface, and the other member consisting of an annulus with a tongue extending around its exterior surface, and means for forcing the two members together.

4. A supplemental tire for vehicle wheels comprising two separable members adapted to fit over the tread of a vehicle wheel tire, one of said members consisting of an annucomprising two separable members adapted to fit over the tread of the vehicle tire, one of said members consisting of an annulus having a flange and a tread and a groove running around its interior surface, and the other member consisting of a sectional annulus having a tongue running around its exterior surface, and means upon the sectional annulus for forcing said sections apart so as to make a firm tongue and groove connection between the two members when in engagement. a

In testimony whereof I affix my signature in presence of two Witnesses.
